Price and rating as shown on Amazon when we collected them. Both change.
The Lenovo A100 is the fifth entry in this guide: a 23.8in Full HD all-in-one in Cloud Grey, with an Intel N100 processor, 8GB of DDR5 memory, a 512GB SSD and Windows 11 Home, listed at £649.00 and rated 4.8 out of 5 from 14 ratings. The stand tilts from -5° to 25°, the listing describes four USB-A ports and an HDMI output, and the box includes a wireless EOS keyboard and mouse.
What that price buys is the interesting part. £649.00 sits 99p under the £649.99 listing elsewhere in this guide, which quotes a six-core i3-1215U with a 4.40GHz turbo, while the guide's £338.81 all-in-one quotes an eight-core i5-12450H. The same Lenovo listing calls the N100 'lightning-fast' and refers to 'robust memory capacity', yet its own spec sheet shows 8GB installed against a 16GB maximum. The rating breakdown is worth reading too: 90% five-star and 10% three-star, which is what produces the 4.8 average, although 90% of 14 ratings cannot be a whole number of reviews. Everything on this page is taken from the Amazon listing, not from testing by us.
